Self-hostee storage for Gmail (lemmy.world)

Not sure if there's a pre-existing solution to this, so I figured I'd just ask to save myself some trouble. I'm running out of space in my Gmail account and switching email providers isn't something I'm interested in. I don't want to pay for Google Drive and I already self-host a ton of other things, so I'm wondering if there is a way to basically offload the storage for the account.

It's been like 2 decades since I set up an email server, but it's possible to have an email client download all the messages from Gmail and remove them from the server. I would like to set up a service on my servers to do that and then act as mail server for my clients. Gmail would still be the outgoing relay and the always-on remote mailbox, but emails would eventually be stored locally where I have plenty of space.

All my clients are VPN'd together with Tailscale, so the lack of external access is not an issue. I'm sure I could slap something roughshod together with Linux packages but if there's a good application for doing this out there already, I'd rather use it and save some time.

Any suggestions? I run all my other stuff in Kubernetes, so if there's one with a Helm chart already I'd prefer it. Not opposed to rolling my own image if needed though.

Basically every serious mailserver package has imapsync included. I don't know what kind of hardware you're running and what you expect from the server doing the copying but running webmail, search indexes, antivirus, etc will cost you ram. There are solutions aimed at keeping backups of your mail though, I can't give you recommendations, the only thing I remember is that they don't give you a normal webmail or imap, instead you get a web-interface aimed at searching through the backup(s)
